“No matter how large, small or temporary the application, there is a security solution.”
With the price of steel going higher, a new type of barrier pro- vides multiple hit capabilities in an open frame barrier design. This barrier is fully-operational after the force of a M50 impact. The fact that no-assist devices are used to operate this electro- mechanical barrier is something completely new to the industry. In addition, the fact that little rebar is needed in the very small foundation is a win for the end user.
BEAM BARRICADES
Crash rated beams are available in hydraulic, electric and manu- ally operated models. They carry ratings from M30 to M50 with penetration levels up to P1 (3’ or less). Adjustable speed options are available with the ability to provide an Emergency Fast Op- eration of less than 2 seconds if required.
Beam barriers are the perfect solution for ingress and egress applications where good vehicle throughput is needed without having to disturb the roadway during installation. The buttresses sit on either side of the road with only the beam perched above it. They are an ideal solution to deter theft from parking lots and used at government facilities, military bases, airports and, public and private entities.
BOLLARDS
Bollards move up and down, and are aesthetically pleasing and allow pedestrians to move between them in non-roadway applica- tions. Manual versions are counter-balanced, and lock in the up or down position, with minimal effort. Models are crash-rated and lowered to allow passage of authorized vehicles. Automated bollards can be activated as quickly as two seconds.
High-security bollard systems operate individually, or in groups of up to 10, and used for intermediate to high-level se- curity applications. Individual bollards are up to 13.25 inches in diameter, up to 39.3 inches high and usually mounted on 3-foot centers. Hydraulic and pneumatic, electromechanical and manual versions can be operated by a variety of control systems.
They are available with a variety of decorative covers and the ar- chitect may design their own cast covers to reflect architectural details of the facility. You can specify cast sleeves of aluminum, fiberglass or brushed stainless steel, all of which slip right over the crash tube. Crash rated bollards may be fitted with an internal warning light for increased visibility and engineered to suit high-volume traffic
Fixed post versions are available to secure the sides of road- ways with the same crash rating and appearance.
PORTABLE DESIGNS
Portable plate barricades provide security against vehicle-based terrorism or thefts for high-cycle locations such as the entrances to large office facilities, government agencies and military bases. Able to deploy in high-traffic locations for full manual or auto-
matic operation within two hours, the quick deployment modular barricades lie level to the ground to allow vehicles to pass and raised or lowered into position using a hydraulic cylinder driven by a hydraulic power unit or manually operated.
Others are self-contained and are stored and towed on their own trailers. Municipalities, event organizers and others that stage temporary events, ranging from farmers’ markets to con- certs and sporting events that need a commercial barrier towed into place to protect attendees as well as against an errant driver.
Towable barricades answer the need of organizations that re- quire a temporary barricade system to protect against a specific threat or secure a facility during special events. The self-contained unit placed in position, controls vehicle access within 15 minutes. Once positioned, the mobile barricade unpacks itself by using hydraulics to raise and lower itself off its wheels. Simply plug in standard 120v or 220v power and you are ready to go. The unit is M40 certified and comes in lengths of 12, 16 and 20 feet.
Portable bollards also offer M30 and M50 protection with easy setup and maneuverability. They can be used in conjunc- tion with the unit described above to provide M50 protection. Portable bollards allow law enforcement and security providers to create a high security special event barricades that block access to temporary venues where vehicles can be used as weapons against large numbers of pedestrians.
SLIDING GATES
From airports to embassies, from warehouses to depots, high- security crash rated gates stop unauthorized pedestrians and ve- hicles from entering places that they do not belong. Some mod- els operate without contact with the ground across the opening. There is a manually operated swing gate and others operate with rack and pinion drives across V-groove wheel ground tracks while incorporating IR safety beam and safety edges. Swing versions are also available.
The clear openings range from 12 to 30 feet. The standard height for all, except the swing gate, is 109 inches. Not only can crash rated gates withstand impacts as high as a 15,000 lb. vehicle striking at 50 MPH and suffer no significant damage, but they also can look good too. Sliding high security gates are powered by either electro-mechanical or hydraulic systems. Perimeter en- try control high security gates are found at airports, power plants, embassies, military installations and government facilities.
NO APPLICATION TOO LARGE OR SMALL
Protecting perimeters of facilities is no small responsibility. Knowing you have the right equipment in place to secure the facility and to prevent human tragedy brings a peace of mind that no amount of money can buy. Carefully
researching available options and consulting with experts will ultimately lead to the right solution.
